Christopher Haster a659c02bbd Added a bot-generated PR-comment with a simple status table 
The littlefs CI is actually in a nice state that generates a lot of
information about PRs (code/stack/struct changes, line/branch coverage
changes, benchmark changes), but GitHub's UI has changed overtime to
make CI statuses harder to find for some reason.

This bot comment should hopefully make this information easy to find
without creating too much noise in the discussion. If not, this can
always be changed later.
